Is a scavenger fish a freshwater fish or a tropical fish?

Freshwater fish. "Scavengers" are native to Latin America, belong to the catfish family, also known as sucker fish, garbage fish, anglerfish, anglerfish, large body, flat head, high dorsal fin, tail side flattened, lips developed like suckers. The whole body is covered with shield scales, and the body surface is rough.

The body is grayish-black or light brown, and the body surface has black and white patterns. Robust and easy to raise. The feeding water temperature is 22 28, and the water quality is weak alkaline hard water.

The bait is mainly algae, and live food is also fed. In the aquarium, it is often attached to rocks, glass to stabilize the body and suck algae, and also looks for benthic animals (such as water earthworms), and is a loyal "cleaner" in the aquarium. It is a nocturnal fish that can be polycultured with healthy species of fish.

Difficult to reproduce in an aquarium. "Scavengers" are omnivorous fish that can eat 3,000 to 5,000 eggs a day, and can also devour fry in large quantities, threatening the reproduction and growth of other fish, and currently "scavengers" have no natural predators in rivers.

Scavenger fish. Also known as sucker fish, anglerfish, angler fish. It is found in Latin America.

Features: Body length 30 cm. The body is large, rounded, with a flattened head, a towering dorsal fin, a flattened tail, and well-developed lips like a sucker. The whole body is covered with shield scales, and the body surface is rough. The body is grayish-black or light brown, and the body surface has black and white patterns.

Feeding characteristics: strong physique, easy to raise. The feeding water temperature is 22 28, and the water quality is weak alkaline hard water.

The bait is mainly algae, and live food is also fed. In the aquarium, it is often attached to stones, glass to stabilize the body and suck algae, and also to look for benthic animals (such as water earthworms), which is the faithful beak of the aquarium. It is a nocturnal fish that can be polycultured with healthy species of fish.

The scientific name of the scavenger is the catfish, the multi-radiated catfish, native to Brazil, introduced as an ornamental fish, because it can swallow fish food, moss, algae, etc. at the bottom of the tank, and is an expert at cleaning up the garbage in the tank, so it is named the scavenger. Its whole body is grayish-black, with black and white patterns, the body surface is rough with shield scales, the head is flattened, the dorsal fin is towering, there are rich suckers, the thorax and abdomen spines can support the body and crawl on land, the dorsal thread is broad, the abdomen is flattened, and the left and right pelvic fins are connected to form a round fan-shaped suction cup. From the ventral surface, it looks like a small pipa, so it is also called a lupa.

The fish has a dark brown body with black spots. The body length can reach 50 cm.

Scavengers are very viable, do not have high requirements for water bodies, can live almost as long as there is water, omnivorous, eat algae, but sometimes also eat worms, insect larvae and other benthic aquatic animals. Particularly harmful is that it will devour fish eggs, about 3000-5000 a day. Sometimes when they are hungry, they will kill each other.

At present, there are no natural enemies in our country, and the harm to local fish and aquatic organisms is very great, and at present, some tributaries of the Pearl River have become a flood trend, so do not discard them into the river at will.

The scavenger fish has hard bones, more bones, less meat, non-toxic, low nutritional value, and because it likes to eat filthy food, it has more bacteria in the abdomen and has a fishy smell. At present, it is less eaten in China, but in Southeast Asia and Vietnam and other countries, some people will eat it, but its skin is more difficult to handle, for example, the picture below requires iron tongs to remove the skin, and its meat is really not delicious.

The scavenger is hot water fish. The water temperature environment of raising scavengers should not be lower than 18 degrees Celsius, not higher than 35 degrees Celsius, when changing the water for the scavenger, the temperature of the old and new water should be basically the same, before it can be replaced, otherwise the water temperature will be cold and hot The temperature difference is slightly larger will lead to death, and the new water can be added with warm water to stir well.

1.To correctly distinguish between cold-water fish and hot-water fish. Cold-water fish, that is, goldfish koi and the like, are very easy to raise.

As long as there is regular tap water, it is enough to change the water every week. The origin of the scavenger is Latin America, so it is a tropical fish, and the scavenger is also known as sucker fish, anglerfish, anglerfish, and can be polycultured with fish of the same size.

2.The origin of the name of the scavenger has something to do with its habits. Scavengers are very omnivorous aquarists, whether it is algae, dead fish carcasses, moss, fish insects, as long as it can be eaten, it eats everything.

3.As a hot water fish, the scavenger should be properly warmed in the winter, because its own ability to survive the winter is low, and not warming will lead to the death of the scavenger.

4.Scavengers are typical hot water fish, scavengers have strong vitality, but they are not tolerant to salt and medicine, so there is no need to sprinkle salt when changing the water.

What freshwater fish are good scavengers?

1. Demersal fish

Debenthic fish are excrement scavengers that help clean up things like plankton, waste, and food debris from fish tanks. This type of fish is usually docile and suitable for beginners. Recommended species include: Mohs catfish, golden thread, Hengfeng fish, carp, etc.

In addition, invertebrates such as shrimp and crabs can also act as scavengers, but be careful not to overdo them in large quantities so as not to deplete the tanks of nutrients.

2. Chronic fatty liver fish

Chronic fatty liver fish refers to fish that rely on fatty meat as a source of nutrition. These fish are usually obese and require less food and have little extra cleaning to stay healthy. Recommended species include: whales, bearded catfish, pufferfish, turtlebackfish, etc.

3. Blue-green algae fish, sea dragon

Blue-green algae is one of the most important nutrients for fish, and fish that like to eat blue-green algae are often useful for cleaning tanks. Recommended species include: violet whales, widemouth sharks, Watden greenmane.

4. Other varieties

Some scavenger breeds do not fall into the above three categories, but they are equally suitable for beginner farming. For example, koi fish, ghost glazed fish, etc., which like to eat algae and zooplankton, can keep the water clean.

In short, when buying scavenger fish, it is necessary to consider factors such as their personality, eating habits and compatibility, and keep the water clean and replace the water during the shut-up period, so that the farmed freshwater fish can grow healthily.

There are no cold water scavengers, which are tropical fish and the water temperature is above 20.

The scavenger is named because he likes to eat the bait and dirt of the aquarium and purifies the water, so it is also known as the sucker fish, the suction catfish, the scientific name is the catfish, which is native to the rivers of South America and can often be seen in Central America.

The fish body is semi-cylindrical, the tail fin is shallow forked, likes weak acidic soft water, suitable for water temperature above 20, the adult body length reaches 30 cm, can not naturally overwinter, active at the bottom of the water body, with strong adaptability, easy to feed, omnivorous, low oxygen tolerance, high catch rate and other characteristics, welcomed by consumers and farmers.

Scavengers are omnivorous fish that feed on moss, algae, benthic animals, fish eggs, fry, and garbage from the water.

1. Scavengers are nocturnal fish, which are often adsorbed on stones and glass in the aquarium to stabilize their bodies and suck algae, and also look for benthic animals such as water earthworms, which are the faithful "cleaners" in the aquarium.

2. The scavenger likes to eat feed, especially the heavy small particle feed, which is convenient for the suction cup to inhale, and for the small particle feed floating on the water surface, it will be sucked by the belly upside down to the water surface.

3. The scavenger's mouth is like a vacuum cleaner, sucking fish feces and green plants into the stomach. It also has a bubble in its mouth, which contains oxygen, so that it can be in the water for a longer period of time, so that it can eat more "food". The scavenger can still clean the walls of the fish tank.

The places it rubbed were exceptionally clean.

4. Scavengers take seaweed, bacteria, and feed as their main food, and will also eat a small amount of fish excrement, fish eggs, and fish fry when they are hungry.

Therefore, scavengers should not raise too much or too much, let alone release them, because if they are reproduced in large quantities, they will devour the eggs of other fish and lead to the extinction of other fish.

The scavenger is not a cold-water fish, but a freshwater tropical fish, the best breeding environment is 22 28 degrees, and its wintering ability is low, the scavenger feeds on algae, aquatic plants, and fish feces, but when the food is sufficient, it will not eat the garbage in the tank, and it is necessary to prevent the scavenger from sucking fish when polyculture with other fish. The scavenger is actually a freshwater tropical fish, it can tolerate a certain low temperature, but the best feeding environment is 22 28 degrees, the scavenger should be properly heated in winter, because its own ability to overwinter is low, and not warming will lead to the death of the scavenger.

The scavenger feeds on algae, aquatic plants, and fish feces, but when the food is sufficient, it will not eat the garbage in the tank, and the scavenger has a good filtration function, because the scavenger itself produces a lot of garbage.

The scavenger has a strong vitality, but it is not tolerant to salt and medicine, so there is no need to sprinkle salt when changing the water, and when it is polycultured with other fish, when other fish are found to be sick, they need to be isolated immediately, because the scavenger will suck the wound of the fish and eat it.
